A blazer is a type of jacket resembling a suit jacket, but cut more casually. A blazer is generally distinguished from a sportcoat as a more formal garment and tailored from solid color fabrics. Blazers often have naval-style metal buttons to reflect their origins as jackets worn by boating club members.
A blazer’s cloth is usually durable, as it is intended as outdoor wear. Blazers are often part of a uniform that denotes, for example, an airline’s employees, students of a particular school, members of sports clubs, and athletes on a particular team.
Blazers are worn with a wide variety of other clothes, ranging from a dress shirt and necktie to an open-necked polo shirt, even to just a plain tee shirt. They are seen with trousers of all colors and fabrics, from the classic white cotton or linen, to grey flannel, to brown or beige chinos, and also jeans.
A fitted, classically cut, double-breasted navy blue blazer with navy-style buttons is a popular design and sometimes referred to as a “reefer” blazer. Particularly in North America and the United Kingdom, it is now frequently used in business casual attire.
Blazers are worn as part of school uniforms by many schools across the Commonwealth, and in a wide range of colors is still daily wear for most uniformed pupils in Britain, Australia and New Zealand. These are blazers in the traditional sense, single-breasted often of bright colors or with piping. This style is also worn by some boat clubs, such as those in Cambridge or Oxford, with the piped version only on special occasions such as a boat club dinner. In this case, the piping is in college colours, and college buttons are worn. This traditional style can be seen in many films set in the Edwardian era, such as Kind Hearts and Coronets
